recently I tried to download PowerShell modules inside my development-image in VirtualBox by using the save-module-cmdlet which leads to this errormessage:
PS C:\Windows\system32> save-module microsoftteams -path c:\temp
WARNING: Unable to resolve package source 'https://www.powershellgallery.com/api/v2/'.
PackageManagement\Save-Package : No match was found for the specified search criteria and module name
'microsoftteams'. Try Get-PSRepository to see all available registered module repositories.

+ CategoryInfo : ObjectNotFound: (Microsoft.Power...ets.SavePackage:SavePackage) [Save-Package], Exceptio

+ FullyQualifiedErrorId : NoMatchFoundForCriteria,Microsoft.PowerShell.PackageManagement.Cmdlets.SavePackage
Trying to connect to the displayed https-url also failed while opening it in browser succeded:
PS C:\Windows\system32> invoke-webrequest https://www.powershellgallery.com/api/v2/
invoke-webrequest : The underlying connection was closed: Could not establish trust relationship for the SSL/TLS
secure channel.
So after hours of checking all possible proxy/certificate/ssl-settings, I found the solution in powershell itself:
Because of reasons I had added the SharePoint-Powershell SnapIn to c:\Windows\System32\WindowsPowerShell\v1.0\profile.ps1 which afterwards broke something so that all connections to https broke.
After commenting out the
Add-PSSnapin "Microsoft.SharePoint.PowerShell" everything works like a charm.If you encounter something similar, try this. And if you try to save changes to profile.ps1 ensure that you opened the file in your editor as administrator. You can test the successful save by adding a write-host-output to the screen. Finally don't forget to close the current and reopen a new PowerShell.
